My husband and I started trying for our second child just after my son had his second birthday at the end of March. I didn't think it was going to happen so quickly, but I had a feeling that I was pregnant and I was having period pain for a fortnight, but no period. So I took two tests and each one was very strongly positive. I didn't have this much "period" pain in my first pregnancy, so that concerns me, plus I don't know if it's worth mentioning that my grandmother was an identical twin. I also don't know if there is any correlation in the high HCG in my urine and the fact that I am nursing my 2 year old son still only some morning about 4 times a week (it's the only way I can get a bit of sleep in).

I am elated about the pregnancy, but didn't expect it to happen so quickly. So my concerns are firstly the period-type pain, and I don't know the date of my last period (if I thought I was going to become pregnant this quickly, I would have taken note), I think it was around my son's birthday in late March.

But my biggest concern is that I have been on holidays and my husband and I have spent about a good 3 weeks binge drinking very heavily. This is a major concern for me and I was wondering if anyone knew of any sort of test that can show effects of alcohol.

I am very worried, so any information would be great.
